Description

[Detailed description of the invention] The present invention is a lid body that is attached to the recess in the refueling part of the fuel tank of an automobile, which normally closes the recess in the refueling part and opens when refueling. This invention relates to a tank lid device.

Conventionally, the lid of this type of fuel tank consists of a case attached to the vehicle body and a lid rotatably pinned to the case, and the case and the lid are usually made of steel plate and are pressed.

Therefore, a lid made of steel plate is heavy, so steel plate springs are used to stably open and close the lid, and the case and lid are assembled using pins, but this process is extremely labor-intensive. It had a big drawback: it was annoying.

The present invention was developed by focusing on these drawbacks, and by molding the case and lid with synthetic resin and utilizing the elasticity of the synthetic resin, the case and lid can be easily assembled with one touch, eliminating the need for pins. It has a unique structure.

An embodiment of the present invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes a synthetic resin case forming an opening 2, and a mounting flange 3 is formed at the edge of the opening 2 of the case 1. In the figure, reference numeral 4 denotes a substantially circular synthetic resin lid, and a pair of rotating arms 5, 5' are integrally formed at one end of the lid 4.

To explain the case 1 and the lid 4 in more detail, the arms 5, 5' are provided with protrusions 6,
6' are each provided protruding toward the case wall surface side,
The protrusions 6, 7' are inserted into the holes 7, 7' provided on the inner wall of the case 1.
Therefore, the arms 5, 5' are rotatable within the case 1.

Now, to explain the installation state of the lid of the present invention, the fuel tank injection port 9 is located in the center of the recess 12 in the outer panel 10 of the vehicle body, and the case 1 is inserted into the opening 13 on the inner wall surface of this recess 12. Once fitted, a pin (not shown) is passed through the mounting hole 11 provided in the flange 3 and fixed to the inner wall surface of the recess 12.

When fitting the arms 5 and 5' of the lid 4 into the case 1 from the opening 2 of the case 1,
Since the arms 5 and 5' are made of synthetic resin, by utilizing the elasticity of the resin, they are compressed and deformed into the guide slopes 17 and 17' provided on the inner wall surface a of the case 1, and are fitted into the arms. When the protrusions 6, 6' provided on the side surfaces of the end portions of the arms 5, 5' are engaged with the holes 7, 7' on the inner wall surface of the case 1, the elasticity of the resin causes the arms 5, 5'
is restored to its original position, and the locking between the protrusions 6, 6' and the holes 7, 7' becomes reliable. arm 5,
5' can be rotated freely.

Alternatively, in some embodiments, a hole 7'' is formed on the arm 5 side, and a protrusion 6'' is provided protruding from the inner wall side of the case 1, so that the case 1 and the lid 4 can be attached rotatably. The mounting of the case and lid is not limited to just one embodiment (see FIGS. 9 and 10).

The lid 4 attached to the case 1 in this manner is rotatable with respect to the case 1, and the injection port 9
It opens and closes a certain recess 12.

Normally, the lid 4 closes the recess 12 and is flush with the panel 10, as shown in FIG.

The back side of this lid 4, that is, the arm 5,
A locking piece 14 is provided at a position opposite to 5'.
This prevents the lid 4 from being opened unnecessarily after being closed (see Fig. 6). Then, when refueling, by operating the lock release from the indoor side (not shown), the locking piece 15 moves back against the spring (not shown), and the locking piece 15 and the locking piece 14 are disengaged from each other. When the lid 4 is pressed, the pressing pieces 8, 8' formed on the bottom wall of the case 1 act on the lid 4. That is, one of the pressing pieces 8 always urges one end of the arm 5 toward its open position, and when the locking piece 15 is released, the lid 4 is immediately pressed by the pressing piece 8, creating a slight gap.

Since the lid 4 can be fully opened by hooking one's finger on this gap, there is no need to form a knob or the like on the lid 4. Therefore, the lid 4 does not protrude beyond the surface of the panel 10, which avoids danger and is also very aesthetically pleasing.

In addition, in order to prevent the lid 4 from closing unnecessarily when the lid 4 is open, the other pressing piece 8' presses one end of the arm 5' when the lid 4 is opened, and presses the end of the arm 5' to prevent the lid 4 from closing unnecessarily. By engaging the pressing pieces 8, 8' with 20, the fully open state can be stably maintained.

In addition, the flange 3 of the case 1 has an arm 5,
Protrusions 16, 16' are provided facing the inner side of the case 1, and when the arms 5, 5' are deformed inward during the opening/closing operation of the lid 4, the protrusions 16, 16' close to the holes 7, 1 of the case 1. 7' to arm 5, protrusion 6 of 5',
This is to prevent 6' from coming off.

In addition, 19 in FIG. 1 is a stopper fixed to the back surface of the lid 4, and 17 and 17' in FIG. This is a guiding slope provided on the inner wall surface.

Next, the locking piece 15 that engages with the locking piece 14 is activated when the lid 4 is returned from the open state to the closed state.
It is constantly biased by a spring (not shown) so that it is automatically locked. Further, as shown in FIG. 7, the locking piece 14' provided on the rotor (not shown) of the cylinder lock 18 provided on the lid 4 is rotated by key operation, and engages with the locking piece 15' fixed to the vehicle body. Engaging and disengaging is performed.

As detailed above, according to the lid device of the present invention, since both the lid and the case are molded from synthetic resin material, it is possible to reduce the weight of the lid and utilize the elasticity of the synthetic resin. By doing so, when assembling the lid and the case, there is no need for steel pins or spring members, making the work extremely simple and cost-effective.Furthermore, the elastic displacement of the arm is reduced by the projections etc. provided on the case. This has the effect of preventing withdrawal from the case due to
